Network mode problem - Galaxy Note 3 Q&A, Help & Troubleshooting

Hello.
I have a note 3 n9005 and when the network mode is WCDMA/GSM or LTE/WCDMA/GSM, my phone stays on GSM often. 3G signal is good in the area, and when I check my friends' phones, I find out their phones are on 3G network but mine is on 2G.
When I choose WCDMA Only, phone registers on 3G network and works without any problem. But switching back to auto connect, cause the phone to register on 2G again after some time.
So is there any configuration that tells the phone to stay on 2G if 3G signal is weak?
Please help if you can.
Thanks in advance.

The cell tower does this by signal quality, and most of the time distance dictates quality. I myself have asked around for AUTO 3G/4G only, but it seems like a subject where nobody has done any research.
Does your 3G signal differ from WCDMA only compared to Auto mode? If so, try updating to a newer firmware, could be a modem/baseband issue that may has been fixed in the mean time.

Technically it should grab the highest network of the three. So LTE has priority over WCDMA, which has priority over GSM. So even if WCDMA has one bar, and GSM 4, it should grab WCDMA until it completely loses that signal.
Have you tested another SIMcard in your phone? It may very well be a SIM problem.

You say it is fault of the cell tower?
So why phones of my friends are ok about this issue and register on WCDMA?
I flashed 3 different lollipop ROMs but nothing changed. ?

Yes. That's exactly what I expect my phone to act about switching between network types.
I never tested another SIM in my phone. So I will check that as soon as possible. I will post the result. Thank you.

Network dies when I turn off 2g

Anyone have this problem? It happens ever time
Sent from my T-Mobile G2 using XDA App
Hmm.... seems like your phone might be in WCDMA mode only... It should be in WCDMA-Preferred since you plan on using 3G and 2G
Go to your phone dialer and dial *#*#4636#*#*
and Diagnostics Menu should come up..... Go to PHONE INFORMATION.... Scroll down and Set Network Type to: WCDMA Preferred
see if that helps...
Thanks for the reply i am on tmobile and it is defaulted to GSM. Will changing it be any different than GSM?
my phone does that as well right now at home even though i have it on WCDMA preferred, t-mo has been having issues with their 4G towers and their DNS servers lately that has been affecting many people with newer phones/SIM cards and in 4G areas, t-mo has not released an ETA on a fix but i have been dealing with it for a month now at my home and i am about ready to switch carriers

Nope, it'll still be the same. WCDMA-Preferred means that then phone will Prioritize 3G/4G signal over an EDGE signal. So If you are in a decent 4G/3G coverage the phone will set itself into 3G/4G mode... and when you move into an area where you have a weaker 3G/4G signal...t han the phone will be in EDGE mode.
Keep in mind that if you're referring about using WCDMA Preferred in a 3G/4G coverage area - but only 2G works - then you have a network issue. This isn't so much a device issue as it is a MSISDN issue on the network or a potential tower issue.
If you get no signal on 3G/4G and signal is there on 2G - check your coverage first - then if coverage shows you should have 3G/4G, call TMO and let them know, they'll need to do a service request or trouble ticket based on the location and breadth of the issue you're having.

Nexus S only shows 3G no H in Taiwan

On my news Nexus S I am only getting and showing 3G with poor connection whether I use Chung-Hwa Telecom or Taiwan's Far Eastone. On my HTC Desire when downloading or uploadinging it would show an "H" up on top and show "3G" if connection was not all that great but with this new Nexus S all I get is 3G. What's up with this? Reception is also worse than the HTC Desire.

Here I see it showing it gets HSDPA.. From what I understand is the 2100 Band in Taiwan is not just 3G
http://www.gsmarena.com/compare.php3?idPhone1=3620&idPhone2=3077
It gets HSDPA also, it just doesn't change icons like cyanogen or like the static H on the G2. It wasn't a widely used icon in america until the networks (T-mobbile and AT&T) upgraded to HSDPA or HSPA+.
It is capable of 7.2mbps download.
You could always check the status of the phone under settings to see what connection you have or wait until cyanogenmod comes out for the nexus s, not just the alpha version.
ya HSPA is still 3G with a max download speed of 7.2 HSPA+ depending on device ranges from like 14.4 to 42

Q: The Nexus S only gets 3G? Omg, I only see a 3G icon!
The Nexus S gets UMTS and HSDPA, which are both technically 3G. Your phone idles on UMTS 3G, and when it starts downloading/uploading, it'll flip to HSDPA after a few moments. You can see this by typing *#*#4636#*#* into your Dialer, going to Phone Info, and looking at Network Type while downloading something. The ability to switch the icons on the notification bar is something that was added in custom ROMS, and is not supported by the stock ROM. Rest assured, if you are on a network that uses the 3G bands the Nexus S supports, then you are recieving HSDPA regardless of what icon you see.

WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

Still sorta understood all that, so should I just leave it where Im at, i mean it is what came with the phone stock after all
As was stated, when an active data connection is formed and there is activity then the status will change under settings. I have an attached screenshot for your viewing pleasure.

PRL is preferred roaming list, iirc. When searching for a network, it'll get preference to those that are on the list over those that aren't. Supposed to be battery savings.

fair enough
I'm noticing this too. I get full HSDPA in the US on AT&T, but when I came to Taiwan and plugged in my prepaid sim for Taiwan Mobile which clearly has 7.2mbps HSPDA in this city, I only get the "3G" icon.
I did do the *#*#INFO#*#* to set my band to Euro which was how data kicked in. But otherwise it only shows "3G." Readingt he posts above, people say it idles on UMTS, but I have AT&T at home and it always shows the H icon. I can never the the H icon in Taiwan.
I have the 9020a which has 850/1900/2100, so I'm not understanding whats going on... Is the lack of 900 3G band hurting me?
Edit: I've been using this phone for 7 months on AT&T now and I just arrived in Taiwan last night....
正常啊。在 系統設定 - 關於手機 - 狀態 裡,看到 行動網路類型,會顯示為 hsdpa。這就是3.5g h了。雖然訊號顯示為3g,實際在支援hsdpa的地方會使用hsdpa的。

[Q] Which Networks To Enable?—CDMA, WCDMA, GSM, etc.?

Hey,
I am on Rogers, in Canada, on the I337M. I have a ROM that allows for the selecting a variety of network modes. By default, the LTE/GSM/WCDMA setting is selected, but there is also a setting for LTE/CDMA/EvDo/GSM/WCDMA. Obviously, that's more networks than are available by default.
What I wonder is if selecting the 5-network option would be a good idea or a bad idea. Would more battery be drained? Would greater reception be gained in sparse areas? Does it depend upon which networks one's carrier uses? If I have no signal, would switching to the 5-network mode potentially enable a 2G signal or something? I don't understand how this works; I just know that LTE is 4G and is the fastest data band and is only partially available in my region currently. I often drop to 3G, but I don't know if that is WCDMA or GSM or what. I looked up these various standards on Wikipedia but still am not clear on everything. To compound matters, Rogers apparently uses HSPA+ as a 3G network and I often see that icon in my status bar, but what is that—WCDMA?
Any light shed on my conundrum would be appreciated.

LTE/GSM/WCDMA simply means your phone will choose the most advancement network automatically. Let's say you are in an LTE area, with this setting you will have LTE. GSM means EDGE (2G) and WCDMA is 3G/3.5G (HSPA+). You will probably conserve battery life if you put it to GSM/WCDMA (auto). It will prefer 3G/3.5G/H+ in LTE areas. I am not familiar with Rogers but it might get you a stronger signal.
Sometimes when the LTE in my area is acting up I'll switch it over to WCDMA only, which helps.
Hope I answered your questions.

Thank you very much for your reply. It was helpful to learn that GSM=EDGE/2G and WCDMA=3G/3.5G (HSPA+). I understand that disabling 4G conserves battery life, and since 4G service isn't as saturated as 3G in my area, perhaps disabling 4G in certain circumstances will be beneficial as the phone will automatically jump to the saturated 3G network.
I'm still not sure about enabling CDMA and EvDo in addition to GSM/WCDMA/LTE. Would it be unnecessary to do so? Would that turn on more radios and drain more battery? Are those networks only available in certain regions, on certain carriers?

LiquidSmooth 2.9 on KToons' latest kernel.
Sorry to revive an old post, but I've been searching all over for this 'simple' question.
What is the difference in LTE/GSM auto and LTE/GSM/CDMA auto? Only APN in use is the T-Mobile LTE APN.
**KEEP IN MIND that while on LTE/GSM and not in an LTE area, I get HSPA and HSPA+ no problem on T-Mobile**
Just wish I could SUCCESSFULLY get 1 of those modes to stick on stock 4.2.2 ROM even with the build.prop edits.

OnePlus Two - HSPA+ and 3G Data Connection Problem

Hi Everyone,
I'm usually just a reader on XDA, but I have found a problem that appears not to have been solved and wondered if anyone had any insight.
Problem Summary
When in an area (or network) with only HSPA and UMTS (strong HSPA/UMTS signal, but with no LTE or 2G available), the phone will drop from H+ to 3G erratically, always dropping the data connection. Traditional phone calls are not affected.
Detailed Description
I have a OnePlus Two and have 2 SIM cards. My first SIM Card is with Bell Canada (Virgin), and the second SIM Card is with WIND Mobile Canada.
Neither Bell nor WIND operate a 2G network, so the lowest the service can fall to is UMTS/3G.
Initially, I didn't notice the problem because Bell also operates an LTE network, and there is no problem with dropping the data connections when on LTE.
When I switched to the WIND SIM card (which only operates HSPA and UMTS), I noticed a problem where the phone would initially connect to H+, begin downloading whatever is needed (say, streaming music), but then part way through the download, the connection would switch to 3G, and the data would effectively stop. Within a minute, the service would jump back to H+ and download some more, but this cycle would continue (H+ --> 3G --> H+ --> 3G... ), with no way of knowing 1) how long the H+ connection would last before dropping to 3G (usually less than 30 seconds), and 2) after dropping to 3G, how long before going back to H+. This problem makes the phone almost useless when there is no LTE.
The most obvious troubleshooting I did was move to locations of better signal but I quickly ruled that out, as nothing seems to remove this problem. Other things I tried was to: move locations in the city, reboot phone, hard reset phone, flash most updated version of Oxygen, unlock bootloader, root, try the HSPA Keepalive app, swap SIM1 to SIM2, and many other things.
I originally thought this was a network issue, but I put this WIND SIM in another phone and there was no problem in any way that resembled this problem.
I also ruled out this being a network-specific problem, as I have taken a trip with the Bell SIM to an area where Bell does not have any LTE coverage (only HSPA and UMTS) and the same problem occurs on Bell as with the WIND SIM.
I have found people who had this problem on the OnePlus One tend to recommend using 2G to stabilize the connection, but this is not possible on Bell or WIND. That solution also would not provide adequate data speeds.
Remember this problem only affects data connectivity, as 3G traditional phone calls have no problems.
Question
Does anyone know if there is a way to adjust the conditions when the OnePlus Two will choose to switch from H+ to 3G?
Does anyone have any easier suggestions?
Thank you all in advance, because this rendering this phone almost useless when there is no LTE coverage.
I believe your problem is that phone it's dualsim standby, that means only one modem that alternates signal for both sims, I think normal would be alternating from faster network to slower network on sim without data.
Having to change to g3 between sims theres something stoped in the modem and data connection is also stopped.
You have no problem with voice calls because other sim is automatically turned off and unreachable.
There's nothing you can do if you're forced to only 3g on both sims
By 3g I mean 3g or h+ which to my knowledge are the same
Hope I was helpful and not wrong or more confusing

Thanks, I will try disabling the second SIM to see if there is a bug with the dual-sim...
What it currently does with the second SIM is it either shows "R" for roaming or just emergency only, but perhaps there is a software issue so I'll see if disabling the second SIM makes a difference.

Though strange, this workaround fixes the issue. Thank you to fburgos for the suggestion!
So just in case anyone ever finds this issue creeps up on them, the solution is to DISABLE the SIM you are not using. It's not the most convenient workaround to swap SIMs, but the other SIM will be in Emergency Mode, so it really makes no functional difference.
On the technical side, it does appear that there is actually a bug in Android for a very uncommon network configuration. It will only appear in this exact configuration:
SIM1: Network has HSPA/3G only, no LTE or 2G to move to
SIM2: Network also only has HSPA/3G with no LTE or 2G
The non-data SIM does NOT connect to a roaming network (connects with "Emergency Only") - if it connects to a roaming 2G network, this problem does not happen.
The data SIM connects to HSPA/3G
Both SIMs are active
I'm not sure if this will happen anywhere else in the world other than having a WIND Mobile Canada SIM and Bell or TELUS Canada SIM
If anyone has insight on how to report this to Google, or someone else who can confirm my theory, that would be great!
Try this:
1. You need to make sure you have the correct LTE APN selected in mobile networks and LTE as preferred type.
2. Go to dialer and type in this: *#*#4636#*#*
3. Phone Information
4. Set Preferred Network Type to: LTE/GSM (PRL) - you an play with which one you wanna use but the one I said works for sure. on other roms I have" TD-SCDMA, GSM/WCDMA and LTE"
5. Now click TURN OFF RADIO and wait WAIT few secs. will that button turns to Turn Radio ON
6. Now TURN ON RADIO and wait
7. when u see the triangle for the signal is back, at least black , go down and lick SMSC REFRESH then UPDATE.
8. now just go back to APN settings and go into your LTE APN
9. Change Bearer to LTE

I have the same problem. Do you already have solved it?
I use only one SIM card so it is not a problem two cards.
really you do not have this problem? if no one knows the solution?
compared with my htc butterfly 2 and another low-end android, one plus 2 running latest Oxygen OS has serious connectivity issues. I compared the signals strength using same sim card in same location (including being connected to the same tower) and One Plus 2 keeps dropping the connection and has really poor signal strength. I have tried the *#*#4636#*#* and tried different network modes, but none of them are helping. Its a real disappointment that the basic feature of this phone is screwed up.
I have tried with CM13 as well. Any ideas if this is a modem version issue?

Signal problem theory/research

Hello, i live in a relatively small town where my service provider has very poor 4G signal. but pretty good 3G signal. With the Axon 7 i have a lot of signal problems that i didnt have with any of my previous phones, where outdoor signal is pretty bad and indoor signal is almost unusable. It also connects almost exclusively to 4G, and in contrast all of my previous phones connected almost exclusively to 3G. Over the last weekend i traveled to a major city where my service provider has very strong 4G signal, and the signal problem was almost non existant. I even had signal in places where other people with the same service provider did not. So my theory is the following, assuming that the hardware (antenna) used for 4G and 3G is the same, it may not be a hardware problem, but a problem with the software having a hard time knowing which band/signal it should connect to. It seems that in my case it prioritizes 4G signal and the cost of a VERY unstable cellphone service. This is also assosiated with the fact that when it connects to 3G (incredibly rare), the phone goes inmediately from 1/2 bars to 4/5 bars. I also changed the SIM configuration to leave LTE out, but either for a visual bug or a software bug, it keeps connecting only to 4G. So could this be the problem that me and a lot of people in low 4G signal zones are having? Is there anyway i can force the phone to connect exclusivly to the 3G signal to test if that is indeed the problem?
Regards!

Without knowing which model Axon 7 you are using, where you are using it, and who your provider is, there is little anyone can do to help you. All I can say is that it helped me A LOT to go into settings and turn off
VoLTE.

U model last update, using it from Argentina, and the provider is Claro. I have LTE disabled in SIM confg as i already said and VoLTE turn of as well but the phone keeps connecting to 4G no matter what i do, even if i configure it to only GSM
I don't think its a matter of position or provider (version could be if different software is provided), but a general issue with the phone and band/signal interpretation coupled with the apparent innability to go off 4G
Refards!

ok when it connects to LTE it says "4G LTE". The 4G that you are getting is probably HSPA or something. And we had someone on here a few months back using Claro in Argentina and they had to seek answers from their Claro

If "4G LTE" is 4G and "4G" is HSPA, when only a "G" appears, what band am i connecting too? Its still pretty weird that im having major signal issues in my town, but when i go to a big city my signal is even better than other phones, it seems inconsistent with the whole "bad hardware" theory. I talked to Claro and it seemed like from their end it was a non issue, can you point me to the thread to see if he got it fixed somehow?
Regards!

/Trolling a bit/
I'm always LMAO when I hear US people talking about that 4G scam (which is H+ for real btw)
G is for 2G
E is for 2G+
3G is 3G
H is 3G+
H+ is 3G++ (an intermediary protocol up to 42MBps)
4G is LTE (up to 150Mbps in the EU most of the time)
4G+ is LTE-A (which is available in most of the EU, SK & JP) - up to 600Mbps, 200MBps in most tests
I've not heard of an app that could modify the way the phone "clings" to 4G LTE, since that might likely be the modem firmware doing it on its own.

Then this is even weirder, because is G is not 3G, but 2G it means that the phone NEVER connects to the major band that all of my previous phones and Claro users connect to. Is there anyway to force to only connect to 3G?
Regards!
i have the G european model, in my town i have bad lte signal 1/2bar, when with my previously xiaomi mi4c was got 4/5 bars (maximum). In the big town i have got in the most of cases 4/5 bars. I think the "signal problems" are relatives of a lack of somehow software. i told this because i've read with the china model with the last updates an improvement of the signal reception of the phone.

You can however force a specific protocol indeed, but you will lack the ability to autoswitch networks. Just download 4G LTE Switch (here) which is a glorified secret code dialer. Just click on prefered network and change at your convenience (4G LTE only, WCDMA only - H+ - and so on). Remember that if you force 4G LTE in an area in which you have no coverage, you won't have internet, and no 2G/3G fallback (so no texts, no calls)
I don't know if this is the same problem, but my wife has an iPhone 6+ and I have an A2017U on B29 stock root. We both use the same network (Movistar Mexico) and while her iPhone often registers LTE, my A7 often registers 4G or even E in the same place. The A7 is receiving the same bands but appears to be "choosing" or locking into the slower protocols more often.
EDIT: NEVER MIND… an xposed module was messing with my network settings. Fixed it. Now I get LTE right away.

What if flash any Custom OS?Would it give better signal ?
